What pulls the FD away from the FW...
What if you take that rubber boot #7 off?
How much checking / inspecting can you do looking through that hole?
It would be hard IMO to turn the engine & FW in small steps.
Maybe take the spark plugs out?
Or Bite the Bullet .....
A great oppertunity to take / post pictures

Another option is that upon installation, the transmission was installed partway, then allowed to hang on the input shaft, bending the centre section of the friction disc. The fact that its cocked would not allow it to slide perfectly on the splines. Unlikely, but then again, its not a common problem we're looking at.
I may have not been clear enough.
As far as I know when you push the pedal down the FD will break contact from the FW and make contact to the clutch housing allowing the FW to move independantly.

My question is. How much room is there between the FD and the FW when the clutch pedal is to the floor?

My question is.
The clutch assy is bolted to the flywheel and rotates with it right ?There are 2 friction surfaces. The FW surface and clutch housing surface. (see my pic above). Why?
The FD has friction material on both sides. Why?
I thought when you push the pedal down, it pulls the fingers back on the PP releasing the force on the FD pushing against the FW. Then the FD rotates with the clutch housing (clutch housing as in that friction surface you can see in the pic above that the FD makes contact with). That being said with the clutch pedal to the floor the clutch PP and FD can rotate independently from the FW.
Clutch ass'y is too vague, a generic term. Gotta stick to the parts.
PP (spring-loaded moving friction surface) is the only thing bolted to the FW.
FD is always trapped between FW (fixed friction surface) and PP surface.
FD is only 'floating' until stabbed by trans input (splined) shaft.
Two reasons for the double faced FD.
1) It creates symmetrical loading in the radial plane only. Splined hub (low friction) allows PP to move away from FW surface w/o any loading in axial direction. This helps keep the friction surfaces all flat and parallel to maximize useful area.
2) All else being equal:
Double the friction area = double the torque
Clever way to double the the torque w/o adding any more weight, eh?
Torque = Spring force x Area X Friction Coefficient
Do this once for each side then add together
were you paying attention? pop quiz next time

That would make sense if that metal ring on the PP actually moved. The only moving part on the PP that I can see is the spring fingers that the TO bearing slides into so the fork can pull back on them.
What part touches the FD to push it against the FW? It appears it is just the TO bearings surface.
